When more than 4,000 new troops in Shamen Town were seized to train in the cold winter of the first month, the construction of the new Shamen Town also entered the high-level period. More than 10,000 people entered the island. In addition to the 4,000 young and strong people who were summoned into the army, they gathered together with their children and some craftsmen and apprentice workers who worked in workshops. Nearly 4,000 women and young girls joined the army to build the city.

Even many half-aged children and old people in their fifties and sixties joined in. Although building a city involves all the matters involved, Li Jing did not say that the people were requisitioning the hard laborers for nothing. In history, requisitioning the people to work freely can easily intensify conflicts between officials and the people, and even the effectiveness of the work was greatly reduced. Li Jing had ordered that the entire city construction project, from the city wall to the residential area, to the construction of the last street lifang, was paid.

People who participate in the construction of the city have registered their work points. The work points are different to different degrees. Even if they do not work hard, the work points they remember are of grade difference. All work points can be exchanged for money and silk in the warehouse in the town at any time, or for food and cloth, etc., and they can even be kept for buying newly built residential houses in the future.

Regardless of men, women, young and old, you can remember as much as you want. Even if a child helps carry a basket of soil or a piece of stone, he will remember it truthfully. In addition, the construction site also includes a meal of three meals, rice and fat slices, which is enough. Under the stimulation of these conditions, the construction of the entire new city went very smoothly.

These few people attracted many people from the two villages of Taishan Village and Beishan Village on the island to join, and even the poor people from the shanty towns of the four wharfs came. At first, Li Jing sent in to recruit only a few poor men. However, these people were a thousand people on the construction site. Not only did they eat three meals and have a mouthful of oil. When they were off work, they went to the manager of the construction site to ask for money. After successfully getting one hundred cents, the second one was not only that they continued to come, but also called all the whole family, the neighbors, and all the neighbors.

Then, it was spread to ten, and ten passed to hundreds. People called friends. The number of cities built on the construction site exceeded the 8,000 mark, and more and more people even came from several nearby islands, and even came by boats around the Dengzhou land area.

With so many entry points, the construction of the new city went very smoothly.

All four walls have been completely demolished, and the new wall base has been dug.

In order to improve defense, Li Jing positioned the new city wall as a crown prism wall with a brick structure from the beginning. However, the city bricks at this time were not cheap. It was impossible to use bricks to build a city of such a large scale. Instead, it was built by rammed earth and then tiles outside.

The entire new city is nearly square, with a length of three hundred steps from north to south, and a length of two hundred steps from east to west, with a circumference of one thousand steps, about three miles, which is equivalent to one-seventh of Dengzhou City. The city wall uses the most traditional rammed earth wall and is then covered with bricks.

The method of ramming earth adopts the plate building method. The plate building ramming earth wall is made of wooden boards, filled with clay and grey stone, and is compacted with a pestle.

In order to improve defense, Shamen Town New Town uses "three-combined soil", namely loess, lime, and sand mixed and rammed. Li Jing also used the suggestions of several old craftsmen's heads, and added brown sugar and glutinous rice slurry to the soil to increase the hardness of the earth wall. The iron nails made of such earth walls are difficult to nail in, and they are still intact after hundreds of years of wind and rain.

Li Jing spent half of his time training recruits in the military camp and half of his time on the construction site. The last time the pirates attacked, a big loss was that they did not have a complete castle defense. This time, Li Jing planned to be in place at one time to build the new city into the most reliable, reliable, safe and safe fortress fortress.

The old craftsman pointed to the foundation of the city wall that had already started to make rammed earth and said, "In order to build a wall, each wall is three feet thick, it is nine feet tall, and it is slanted to close, which is half the thickness; if the height is three feet higher, it is one foot thick, and the reduction is the same as it is."

"According to the general's requirements, the city wall of the new city will be as high as six zhang. According to the method of building a city, the base of the wall is half the height of the city, three zhang wide. The city is one third of the thickness, and the city is two zhang thick. The above is slanted, the thickness is half, and the top of the city wall is one zhang thick. This is the first time that I have built such a castle. I am afraid that it will be as solid as a golden soup from now on, and it will be broken for thousands of years."

When building cities in the Tang Dynasty, the construction of cities was generally mainly rammed earth walls, and there were also adobe brick walls, stone walls and brick walls. In comparison, stone walls and brick walls were the most solid, but pure stone walls and brick walls were expensive and were not easy to build too tall. The city walls were made of bad soil and bricks and brick walls in advance and then built up bricks. This method was faster, but it was not strong enough. The rammed earth walls were made of rammed earth and were the thickest, and the thickness of the city walls was often one or two meters thick, which was rough and resistant to attack.

After careful consideration, Li Jing finally chose the rammed earth wall. However, in order to add defense, he also asked to bread a layer of bricks on the outside of the rammed earth wall. In this way, it was rough, thick, and strong. The three-piece soil made of loess, lime, and sand was added, and glutinous rice slurry was added to make the most bonding and strong glutinous rice mortar, and then made with branches of red willows or reeds.

The construction papers were clamped up with the templates, and countless men and women built the city construction workers heated the iron nest, heated the loess and stir-fried into the soil. There were also wall screens to screen the soil and built the plate. There were specially mixed and mixed cooked king and lime, and sand made three-piece soil. There were also special picking soil to send soil and pouring it into the construction paper, and then there were special holding a ramming pestle to compact the soil over and over again. In addition, some women held large clappers and small clappers followed the back. The whole process was very complicated, with dozens or hundreds of processes. However, there were more than a dozen old craftsmen working on the construction site, and there were many experienced craftsmen instructing it, and everything was orderly.

Seeing more than a dozen old craftsmen rigorously checking the processes, Li Jing also sighed in his heart that building a city is so complicated. It is so complicated that even the soil for building a city needs to be fried in a hot pot. The old craftsman reached out and grabbed the fried soil in his hand. He squeezed his hands tightly, and the soil in his hand formed a ball. After he looked at it, he threw the soil on the ground, and the soil dispersed as soon as it landed.

The old craftsman explained to Li Jing, "Control the moisture content in the soil during ramming is the key to ensuring the quality of the soil wall. The moisture content is too little, the soil is sticky, and the texture of the rammed soil wall is loose and obviously not strong; the moisture content is too much, the soil wall cannot be compacted, and the wall is prone to shrinking and cracking after the moisture evaporates. Therefore, strict control must be carried out during construction. According to experience, the cooked soil can be tightly pinched into a ball, and if it is thrown away, it is considered as the moisture is appropriate."

Li Jing watched all the way and gained insight.

Construction of four walls was started at the same time, and the base of three meters wide had been completed. The workers built rammed earth and built a city wall that was nearly ten meters high. Li Jing saw that the foot of the wall was specially made of pebbles. According to the craftsmen, this was to prevent rainwater from soaking.

The entire city wall gradually thins from the bottom layer, with the outer skin slightly closed, and the inner skin is layered and the platform is returned to the table, which is reduced by 3 to 5 inches in each layer, which is more stable in structure and reduces the weight of the wall body. In order to increase the overall structure of the wall, reinforcement is also provided in the earth wall, that is, "wall bones" are set horizontally. The method is to split bamboo into long bamboo pieces more than one inch wide, and sandwich it into the rammed earth wall. A layer of bamboo tendons is placed every three or four inches in the height of the wall, with a horizontal spacing of about 6 to 7 inches. Since the upper and lower beams of the middle and upper beams of the rammed building are staggered at each layer to avoid crossing the gap, the bonding of the wall bones greatly enhances the overall wall.

In addition, tamping is carried out in an orderly manner in stages, usually in several stages: the first stage is tamped with eight plates, each plate is one foot three, and then stop for half a month. In the second stage, when the wall is dry to a certain level, the first stage tamping method can be repeated, and the second eight plate is tamped until the top floor. In this way, the tamping of the wall is more strong, and it takes three months to complete the entire rammed earth stage of the city wall.

After the rammed earth wall is built, there is no need to wait any longer, and the earthen wall can be wrapped in bricks immediately. The bricks used are larger and stronger than those of ordinary houses. As early as the beginning, Li Jing had invited bricks and crafted bricks at the foot of Fenghuang Mountain. After the earth wall is rammed, the bricks will be basically burned. In addition, when wrapping bricks, glutinous rice mortar made of lime, sand, and glutinous rice mortar are specially used to bond the brick wall. According to the craftsmen, this glutinous rice mortar has been used in the Northern and Southern Dynasties. Its strength is greater than that of ordinary mortar, and its strength is greater than that of pure lime mortar, which is extremely strong and more water-resistant.

The shape of the city wall was not completely square, but according to Li Jing's requirements and drawings, the city wall was built into a crown-shaped city wall with countless ridges, greatly improving the defense ability of the city wall. In addition to the four city gate towers on the city gate, there will be a thousand three-meter-high arrow towers on the city wall, and a corner tower will also be built.

In addition to the four gates in the southeast, west and north, four urns will be built to protect the gates. The four urns will be built into four small crown castles in accordance with Li Jing's requirements. Then, around the entire new city, a moat that is ten feet wide and two feet deep will be excavated, and live water will be introduced from the foot of Phoenix Mountain.

Six feet high, three feet high, two feet thick, and one meter wide on the top of the city. Once the new city wall is completed, it can be achieved by one to seven or even ten. As long as the four thousand soldiers in Shamen Town retreat to the city, stock up enough food, and equip the city with crossbow beds, strong bows and hard crossbows. Even if more than 30,000 or even 50,000 soldiers and horses attack, they will definitely support more than one year. With such a fortress fortress, even if Shamen Town is surrounded by Feng Zhang and Wang Jin, Li Jing will not be afraid at all.

"It only takes half a year, and the castle will be completed in half a year!" The old craftsman looked at the new city that had just begun to show his glory and said excitedly.
Chapter completed!
